Water Purification Device

Abstract

A water purification device which can process contaminated water, and upgrade it to a potable quality or other secondary useful purposes such as irrigation, shower or laundry and general water. This is achieved without the use of chemicals or membranes. The device consists of a geometrical configuration of riser and connecting tubes for contacting ozone and ultraviolet (UV) light with said contaminated water in order to provide an advance oxidation environment, resulting in disinfection, a reduction in biological activity, chemical oxygen demand, organic species and other water-borne contaminants such as fungi, molds algae, bacteria, viruses, protozoa, oils, fats, tastes and odours. The geometrical configuration of contacting the ozone, UV and water, combined with an ozone injection system that results in optimum disinfection of the water.

Description

[0001]This invention was made with the support of Worldwide Water Technologies Sdn Bhd, and as such Worldwide Piping Products (M) Sdn Bhd has the rights to this invention.FIELD OF THE INVENTION[0002]This invention relates to medium scale (1 m3 per day to greater than 500 m3 per day) water purification devices, their method of making and their method of use.BACKGROUND OF THE INVENTION[0003]Upgrading water, which has chemical or biological contaminants; to a degree such that it can be useful, is a major challenge in many areas of the world. Currently, water purification systems are mostly large-scale, such as municipal sewage treatments works (STW) or reverse osmosis (RO) plants. Both provide a quality of water which is fit for purpose, but both have significant environmental negatives. STW plants require the chemical addition of substances such as chlorine and iron sulphate, both of which have a financial and an environmental cost. As for RO there are the significant financial and en...

Benefits of technology

[0014]Accordingly, the above disadvantages of prior art are overcome by the present invention which provides a water purification apparatus comprising a horizontal pipe inlet, to a series of riser tubes which contain UV lamps and act as risers for the counter

Problems solved by technology

Upgrading water, which has chemical or biological contaminants; to a degree such that it can be useful, is a major challenge in many areas of the world.

Both provide a quality of water which is fit for purpose, but both have significant environmental negatives.

STW plants require the chemical addition of substances such as chlorine and iron sulphate, both of which have a financial and an environmental cost.

As for RO there are the significant financial and environmental costs of the RO membranes, which clog and need frequent replacing.

This more contaminated stream, which generally contains high levels of salts, most frequently sodium chloride, is a common environmental problem as the more contaminated stream requires disposal in the environment.

The result of this disposal often has a deleterious effect on local wildlife and ecology generally.
